Oil Filled Rotary Vane Pumps

SV series single-stage oil-filled rotary vane vacuum pump is a reliable, durable, economical and adaptable range of vacuum pumps.

In the circular pump body, is an air suction valve and exhaust valve (stator). The vanes are equipped with an eccentric slot in the rotor. The vane blades divide the pump chamber into three parts. The volume of the pump chamber keeps changing periodically as the rotor rotates to finish the process of gas suction, compression and elimination.

Dry Screw Vacuum Pumps

LG series dry screw vacuum pumps can manage both condensable vapours and some solids with no residue. They offer a number of advantages over the traditional vacuum pump designs. There’s is no oil or water in contact with the process vapours, so therefore they are considered environmentally friendly.

Two Stage Oil Sealed Pumps

2XZ series direct-driven rotary vane vacuum pump is one of the main types used for pumping gas from sealed vessels. It not only can be used alone, but also can be a backing pump for booster pumps, diffusion pumps, turbo molecular pumps and titanium pumps.

It can be used for electric vacuum device manufacturing, thermos manufacturing, vacuum welding, printing, plastic, refrigeration equipment repair and instrument repair facilities, etc.
